The Department of Disaster Prevention and Mitigation (DDPM) issued a flood warning for Samut Prakan at 11.20am on Wednesday (September 30, 2026), as some water from eastern Bangkok is being drained to the sea through the province.
Flood levels in Bang Phli, Bang Bo and Bang Sao Thong districts are expected to remain steady or fall only slightly for about 7–10 days.
Residents were urged to beware of flooding and electric shocks and to move vulnerable people to safety.
Those needing assistance were advised to contact local administrative organisations and the subdistrict and village heads in their area.
DDPM worked with mobile network operators Advanced Info Service (AIS), True and National Telecom (NT) to send Cell Broadcast flood alerts to people in Bang Phli, Bang Bo and Bang Sao Thong districts in Samut Prakan.
Members of the public can report incidents and request assistance through the LINE ID @1784DDPM, or by calling the DDPM hotline on 1784, available 24 hours a day.
